HARROW.

SPECIFICATION forming part of Letters Patent No. 749,158,,dated January12, 1904:.

Application filed August 19, 1903.

To all whom it may concern.-

Be it known that I, BENJAMIN FRANKLIN BRAKEBILL, a citizen of the UnitedStates, residing at Pinhook Landing, in thecounty of Meigs and State ofTennessee, have invented new and useful Improvements in Harrows, ofwhich the following is a specification.

My invention relates to improvements in harrows, and more particularlyto expansible harrows; and it consists of novel means for readilyadjusting the wings or sections in relation to each other and retainingthem in their adjusted position, together with other novel features tobe more particularlypointed out in the following detaileddescription.

Referring to the accompanying drawings, forming part hereof, wherein apreferable embodiment of my invention is disclosed. for the purpose ofillustration, Figure 1 is a top plan view of my harrow with portions cutaway. Fig. 2 is a side elevation. Fig. 3 is a crosssection on the lineat a: of Fig. 1, and Figs. 4 and 5 are'detail views.

Referring now more particularly to the drawings, wherein like referencecharacters designate corresponding parts in the several Views, Adesignates angularly-arranged outer beams for the harrow, and Bsimilarly-arranged intermediate beams, thus forming a pair of beams orwings A B upon the opposite sides of the harrow, all of said beamshaving the usual teeth a projecting therebeneath. Arranged to rigidlyconnect the adjoining front ends of the intermediate and outer beams aresuitable nose-plates'C. Secured to the outer beams A at a point adjacentto the front ends thereof are upwardly-curved arms D, terminating attheir upper ends in a straight portion (1, to which is pivotally securedat d a bridge-piece E. Extending rearwardly from the bridge-piece E andconnected thereto is an elongated longitudinal bar F, having transversecross-plates G and H, slightly curved throughout their length and havinga plurality of apertures g and h, respectively, therethrough. Arrangedto support the bar F at its forward end are upwardly-extended bracketsI, having feet '6, secured by bolts 2" to the outer beams A and havingat their upper ends the opposite sides of the harrow. The brackets Kterminate at their upper ends in outward extensions K, having aperturessaid apertures arranged to register with the apertures 72. of thecross-plate H, through which registering apertures pins J "are adaptedto pass to connect the parts H and K in adjusted positions. L arehandles extending upwardly and rearwardly from the forward end of theintermediate beams B; Brackets M, having elongated feet M secured to therespective pairs of beams A B by bolts on, are arranged to pass throughears Z on the handle L and have inwardly-turned extensions i passingover the handles, said extensions having fiat overlapping ends on, witha series of registering apertures m, through which is passed a pin J,whereby the overlapping portions are connected. I

The operation is obvious. When it is desired to adjust the relativepositions of the pairs of beams or wings A B, the pins J, J, and J areremoved, when the beams A B will be free to swing inwardly or outwardlyfrom their respective pivots d" through the instrumentality of thehandles thereon. When the desired angularity: of the beams is obtained,the pins J, J, and J will be again passed through the appropriateregistering apertures, which will retain the parts in their adjustedposition while the operation of the harrow is proceeded with.

tween which bridge-piece E and member f any suitable draft attachment 0,apertured at 0, may be placed and secured by a bolt 0. Many minorchanges may be made in the details of the construction of my devicewithout in the least departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a harrow, the combination of outer beams, having upwardly-curvedarms at their forward ends, a bridge pivotally connecting the arms, alongitudinal bar extending rearwardly from the bridge, a transverse barse; cured thereto and having a series of apertures therethrough,intermediate beams secured to the outer beams, brackets secured to theintermediate and outer beams, and having flanges at their upper endapertured complementary to the apertures in the transverse bar, and apin arranged to pass through said complementary apertures.

2. In a harrow, the combination of outer beams having upwardly-curvedarms at their forward ends, a bridge pivotally connecting the arms,intermediate beams secured to the outer beams, a rearwardly-extendinglongitudinal bar secured to said bridge, supporting-brackets for thebar, secured to the outer beams, and an adjustable connection betweenthe same and the bar, supplemental brackets secured to and extendingbetween the intermediate and outer beams, and an adjustable connectionbetween said supplemental brackets and the longitudinal bar.

3. In a harrow, the combination of the beams having a pivotal connectionat their forward ends, handles on the beams, ears on the handles,brackets on the beams, said brackets passing through the ears on thehandles, and an adjustable connection between the inner ends of thebrackets.

4:. In a harrow, the combination of outer beams, intermediate beamssecured thereto, handles upon the intermediate beams, ears upon thehandles, brackets secured to the intermediate and outer beams andpassing through the ears of the handles, and an adjustable connectionbetween the inner ends of the brackets. v

5. In a harrow, the combination of outer beams, a bridge pivotallyconnecting the forward ends thereof, intermediate beams secured to theouter beams, a rearwardly-extending longitudinal bar secured to saidbridge, supporting-brackets for the bar secured to the outer beams, andan adjustable connection between the same and the bar, sup- -plementalbrackets secured to and extending between the intermediate and outerbeams, and an adjustable connection between said supplemental bracketsand the longitudinal bar.

6. In a harrow, the combination of beams, having upwardly-curved arms attheir forward ends, a bridge pivotally connecting the arms, alongitudinal bar extending rearwardly from said bridge, a curvedtransverse bar secured thereto and having a series of aperturestherethrough, brackets secured to said beams and having flanges at theirupper ends aperturcd complementary to the apertures in the transversebar, and a pin arranged to pass through said complementary apertures.

7 In a harrow, the combination of beams having upwardly-curved arms attheir forward ends, a bridge pivotally connecting the arms, arearwardly-extending longitudinal bar secured to said bridge,supporting-brackets for the longitudinal bar secured to the beams attheir lower ends and adjustably secured to the bar at their upper ends,handles on the beams, ears on the handles, supplemental brackets on thebeams passing through the ears on the handles, and an adjustableconnection between the inner ends of said supplemental brackets.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
